I have a 2004 Southwind and when I plug onto shore power (110 not 30amp), via the coach power cord, the shore power fuse blows, at the house (not the breakers in the MH) when I have the converter plugged in. As long as converter is unplugged shore power works. When I plug the converter back in the shore power fuse at the house (not MH) fuse pops.

I have plugged only the converter into a separate shore power source and it will still blow the shore power fuse. I have checked the output of the intel PD9160A and it is putting out Approx 13.5. Batteries are good and wired properly.

If I disconnect the positive battery cable from the converter and plug the converter into a separate shore power and then reconnect the positive battery lead back to the converter the converter then works and charges the batteries, however if I am plugged into shore power via the coach power cord it somehow will still trip the shore power fuse at the shore power fuse panel (not the MH panel).

When the generator is running everything seems to work just fine.

Is the house breaker a GFCI? Many MH don't like to be plugged into a GFCI and will trip it.

Not on a GFI circuit. I think the problem is the shore house breakers. Although they are 20A they still pop. Is it possible that they have gotten weak as a result of being popped to many time?? I am now plugged into another socket with only a 15A breaker and it is working. Opinons welcomed.

Thanks

Is it possible that you just have too many things turned on in the motorhome? The electric hot water tank for example?

Everything was turned off. The only thing on was power converter. I am now plugged into a different house socket with only a 15A fuse and everything is OK. I have plugged the microwave, two TV's, and coffee pot in and fuse still holding. Even tried our coffee bean grind and fuse held.

Still welcome opinions and comments.

Thanks

Check that outlet for correct wiring, i.e. reversed hot & neutral, reversed neutral and ground, etc. One of those $5 outlet testers will give you a quick answer on that score. Not sure just why that would trip a breaker (or is it really a fuse?), but it's an obvious potential difference between outlets. And a common problem in older homes or amateur outlet replacement.
